Mercury topically sets the rev limiter 150 to 200rpm higher than the maximum recommended rpm for a given engine.
The max recommended rpm for your engine is 5200rpm correct? Likely the rev limiter is set at 5350rpm...
Yes, the components used to build the 600 would likely work without failure to 5500-5600rpm. It is a bit more complicated than just changing the rev limiter in the computer though. The fuel mapping would also need to be changed to allow for the proper mixture at high rpm or the engine would run lean.
Another thing to consider are the valve-train components used. Even if you did spin the engine faster, would it actually make more power? Probably not, because the cam shaft used was likely designed to make peek HP at around 5200rpm in this 502 cube engine...
I maintain that the best way to get more HP out of your 600 is to turn up the boost...
From speaking with different prop gurus, I would say prop your boat to reach 5200-5300rpm with a vary light load. And I would define a vary light load as 1 person and 10 gal. of gas...
